Temperature Monitoring In Water Heating System Using Control Temperature With Pid Ziegler Nichols Method Web Based

Many industries use heating for the production process. But the problem is that this heater must be controlled to its temperature so that the hot temperature in accordance with the desired, because if uncontrolled heat will lead to overheating and over pressure that will cause the production process to fail. To control the heater then used the on-off method and PID method which is a method to determine the precision of an instrumentation system with the characteristics of feedback on the system. On the control result using the on-off method to address the time when the process of heating water from the initial temperature of 36.69 to the desired temperature value 73 that is 8 minutes 14 seconds while in the heating process using PID from the initial temperature of 29.56 to the desired temperature value 73 that is 19 minutes 14 seconds. Temperature value can be seen in the web display either in the form of numbers with units of degrees Celsius or in the form of graphs. While the result of testing tool to user acceptance / respondent shows that variable of PU (X1) and variable of PEU (X2) to receipt of BITU (Y) user is acceptable. This is indicated by the reliability test with the value of croncbach's alpha PU 0.759> 0.60, PEU 0.669> 0.60, PU and PEU validity show r table value higher than t table, multiple linear regression tests PU (X1) and PEU (X2 ) to the receipt of BITU (Y) users shows significant value 0,000 <0.05, the summary summary model shows the value () = 0.262 and anova attributes the Sig value.
